A 1.0108 g sample of an unknown nonelectrolyte is dissolved in 10.0090 g of benzophenone and produces a solution that freezes at 35.8 C. If the pure benzophenone melted at 48.1 C, what is the molecular weight of the unknown compound?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks. energy was destroyed inside the blocks. energy was absorbed into the blocks from outside the system. energy was transferred from the warmer block to the cooler block.
